Guru vs Prowlarr: at a glance
What is Guru?
Guru's Knowledge Agents get the plumbing that makes their answers checkable and safe.
Guru's late-October releases all serve the Knowledge Agent. Agents can now return the records behind an analytical answer, read SCIM-provisioned profile attributes such as department and manager, and choose from sources admins can rename. On the governance side, DLP masking now covers what users type before it is logged or sent to the LLM, and each agent gets its own chat retention window of 1 to 90 days.
What is Prowlarr?
Prowlarr adds Trusted Networks and host validation, then moves to 2.7
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.

Guru's Knowledge Agents get the plumbing that makes their answers checkable and safe.
◆ Current state
Guru's late-October releases all serve the Knowledge Agent. Agents can now return the records behind an analytical answer, read SCIM-provisioned profile attributes such as department and manager, and choose from sources admins can rename. On the governance side, DLP masking now covers what users type before it is logged or sent to the LLM, and each agent gets its own chat retention window of 1 to 90 days.
◆ Where it's heading
The arc runs from giving agents write access to making them auditable. Mid-October brought a rebuilt Teams app with AI answers, MCP image uploads into card drafts and answer editing for skills-based agents; late October shifted to data controls and to answers that show their workings. Guru is treating the agent as the main interface and the card base as what it works on.
◆ Prediction
Expect the stated Mermaid gap in Slack, email and exports to close, and more per-agent settings in the Guardrails section where retention now sits.

5.0COLLAB
Prowlarr adds Trusted Networks and host validation, then moves to 2.7
◆ Current state
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.
◆ Where it's heading
Security settings that limit which hosts and networks can reach the app are the main thread since September, rolled out in step with Lidarr. Indexer definitions keep getting small compatibility fixes.
◆ Prediction
More indexer-level fixes and Allowed Hosts follow-ups are likely in 2.7 patches.
